ATTACHMENT FDR TOOLS.

Specification of Letters Patent.

Application filed June 12, 1912.

Patented Aug. 4, 1914.

Serial No. 703,351.

T all whom it may concern Be it known that I, FRANK WV. W'nrrn, a citizen of the United States, residing at Brooklyn, in the county of Kings and catate of New York, have invented new and useful improvements in Attachments for Tools, of which the following is a specification.

The present invention relates to a holding attachment for rivet sets, chisels or similar tools employed in connection with pneumatic or electric hammers, and resides in the construction, combination and arrangementof parts set forth in the following specification and falling within the scope of the appeiuled claim.

.In the drawing, Figure 1 is a side elevation of my improvement in applied position. Fig. 2 is a top plan view of the improvement detached, parts being shown in section.

It well known to those familiar with the operation of pneumatic or electric hammers that the trigger for operating the same is extremely sensitive and that when the hammer ten'iporarily withdrawn from its work and laid aside, a jolt or jar of the scail'old upon which the said hammer is supported will accidentally operate the trigger and cause the rivet set or chisel to be projected therefrom at a great velocity. The trigger is also liable to actuation by a worlmnan accidentally contacting the same with his 'Foot or hand, by tools or timbers being carelessly thrown upon the scaffold or othersupport upon which the hammer has been temporarily laid and which contact with the trigger of tin. hammer, and from other in numorable causes which will accidentally actuate the piston of the ham mer.

In the drawing, the numeral 1 dt signatcs an ordinary pncunmtic halmncr, having theoperating trigger 2 and being provided with a suitable tool 3, such as a rivet set. The handle 4- of the hammer is of the conventional U-shaped construction. and as the working parts of the hammer do .uot form any part of the present invention, the same will not be referred to in detail.

The numeral 5 designates my improved tool holding; device in its entirety. The device contemplates the employment of a split ring (3, which is adapted to be arranged upon the tool. 3 and to contact with its flange or head or that portion oi the said tool opp r site its shank, the latter being re eived within the hammer proper. Iivotally connected as at 7 between the offset ends of the split ring (3 is rod 8 which has one of its ends provided with a head 9. This head 9 adapted to be received within a cylinder 10, the said cylinder having one of its ends open and threaded. The numeral 1] designates a cap for the said threaded end of the cylinder. This cap is provided with a threaded bore J2, and the said cap is further provided with a reduced extending finger 13. livotally connected as at H with the finger '13 are the offset ends 1.5 provided by a substantially split U-shaped manner 16, and this member is adapted to be positioned upon the handle -lot' the hammer opposite that portion thereofupon which is arranged the trigger 2. Surrounding the rod S'and exerting a pressure between its head 9 and the closed end of the cylinder 10 is-'a helical spring 17, the latter being provided in order to compensate for the shock on jar incident to the o cration of the piston o the hammer when the trigger 2 has been ac..:identally contacted and also to permit of thc tool 3 being elected from the hammer a slight distance, the said distance however, not being sullicicnt to permit of the shank of the tool leaving; the bore ol' the hammer.

Either or both of the pivots 7 and 14 may bc'rcmovablc, and it will thus be noted that the device may be easily and quickly positioned upon the hammer, and from the above description, taken in connection with the accmnpanying drawing, the sim 'ilicity of the device as well as the advantages thereof will commend themselves, it is thought, to those skilled in the art to which SHL'lIjlDVQI'ltlODS ap'pcrtain without further detailed description.

While the device has been described and illustrated as connected with the handle of the hammer, it is, to be understood that the same may be connected with equal cfliqiency to the barrel of the said hammer.
